TOXIC AND OXYGEN GAS DETECTOR

차량정보 표
Model No. TOXIC & OXYGEN GAS DETECTOR Model : QM-4700
Category GAS DETECTOR, TOXIC AND OXYGEN GAS DETECTOR

Description

Description
  • TRANSMITTER TYPE(4~20mA)
  • MODEL : QM-4700
Features
  • Ambient diffusion gas detector equipped with toxic and oxygen-sensitive sensor
  • Gas detector with dedicated gas detection principle, providing excellent selectivity and minimal interference from other gases by reacting specifically to the target gas
  • Internal pressure explosion-proof
  • Calibration and program setting ZERO point, Span ( Automatic Setting with no Volume except for 4~20mA)
  • Calibration and maintenance by one person
  • Minimization of the impact of noise - temperature/humidity
  • Connection of the analog standard output(4~20mA) signal to DCS & PLC monitoring system
  • Install the system in hazardous areas at industrial sites to measure combustible gases in real-time, and provide 4~20mA standard output and connect to control devices, alarm devices, and monitoring systems
